ject of this invention is. to ereby the packing material subject to a yielding pres. ak-proof pipe joint. An'- other object -is to provide meanswhereby the pressure on the packing maybe 'adjusted to suit the fluid and the hydrostatic pressure at which the latter is operated. A further object is the provision ,of a liexible or rotary pipe joint of this character which is simple in construction, ellicient a can be manufactured at relatively low cost.

Additional features and advantages of this invention will appear from the following description considered in connection with the accompanying drawing forming a part of this application and in which:

The gasket ring has contact-lugs 12 which bear against the collar 7, and .apertures 13 are drilled through the sleeve member vto enable 'the Huid carried in a line to 'exert pressure on .the gasket ring., .A coil-spring 14 is placed on the sleevecto bear against the outer side of the follower. 4The pressure exerted by said si ring may be regulated by means of 00 a threadhd nut 15- whichen threads cut olitw suitable size to` provided with'one whichengage cut a. central aperture 18 of fit about the sleeve and or more fiat portions 19 j lar flats'20 cut on the sleeve member for the 79 l ose of preventing the' rotation of the er about saidsleeve. Lugs 21 are also rovided on the washer to be `bent over the at sides of the nut 15 to prevent same 'fromunscrewing. At the outer end ofthe sleeve is cut the pipe-thread 22, by which the joint 1s connected tothe pipe line, and the intermediate space 23 between said thread and the iit is used' isa a wrench-hol?, the(v so aor' a o i sul-acetoVV o the sleelirllgwhigle thrlllzmi being screwed against the spring. be understood, -the pressure exerted by the Nspring against the ollower tends to compress theV pac and force it radially against the large bore in the body,v and the sleeve member, thus preventing any leaks. Moreover, on account of the lockwaslers the nut will always rotate with thezsleve and maintain its'adjustment. 90

The rotary sleeve 8 withthe ments mounted thereon are kept within the -bdy 'portion .by the bonnet 4,

, of `which is bored at the center diameter than the"'outside 'di follower-ring, thus acting as a `stop for the vj latter. If desired, the Y sh ll 3 may be lngthened to allow for a longitudinal movef ment, soLcalled traverse, of the sleeve-rnember therein, asfsugg'ested in Fig. '1, b'y the lo packing elescrewed on socket-nut within the correspon l is connected to a pipe struction and wardly until t e latter bears against t e cap 24; of the bonnet 4, and that the gasket is suilcientl joint.

Experience as also shown that pipe-joints o this character, eslciall' when .used on 'steam' are lia le to leak when the steam is turned oi on account of unequal contraction of th'e-various parts of. the jo'int, which condition ows the water of condensation to drip out the joint. This defect ispractically overcome in my invention because of the prgssure exerted constantly by the coil spring on the compressible gasket.

In Figs.`4 and 5 I have tion of mygasket compressing arrangemen in connectionl with a universally flexible spherical ipe-joint. This exible joint consists ma' y of the anged socket-cup 25, the 5 26 and the sleevemember 27 having a collar 28 the riphery of which is turned spilpric'ally to t snugly gly bored socket-cup sleeve is mounted the side o f which the fol.

lower-ring 30 is forced by the coil-spring 14 whose tension is adjusted, as in the above mentioned rotary by the threaded nut oint, 15, locked bythe ook-washer 16.- Flat surshown the applicaand nut. Upon this gasket 29 against the -faces 20 are also providedon the" sleevemember to prevent the relative motion between'fthe latter andthe lock-washer. This flexible pipe joint is of the straight type and line by means of the threaded apertures 31 and 32.

As will be understood, as suggested herein, there may be slight changes made in the conarrangement of the details of Y inv invention without departing from the lield and scope of the sime, and- I intend to include all such variations, as fall within .the
